On each trial of a digit span memory task, the participant is asked to read aloud a string of random digits. The participant must then repeat the digits in the correct order. If the participant is successful, the length of the next string is increased by one. For instance, if the participant repeats four digits successfully, she will hear five random digits on the next trial. The participant's score is the longest string of digits she can successfully repeat. A professor of cognitive psychology is interested in the number of digits successfully repeated on the digit span task among college students. She measures the number of digits successfully repeated for 49 randomly selected students. The professor knows that the distribution of scores is normal, but she does not know that the true average number of digits successfully repeated on the đigt span task among college students is 7.06 đigits with a standard deviation of 1.63 digits. The expected value of the mean of the 49 randomly selected students, M, is - (Hint: Use the population mean and/or standard deviation just given to calculate the expected value of M.) The standard error of Mis - (Hint: Use the population mean and/or standard deviation just given to calculate the standard error.)
